Not a bad little game. All I could think of was "Shitty Myst" while playing it. But I still liked it. Crude 3D environments but some good atmosphere music. A couple puzzles were bad but most were alright. If you liked games like Antichamber you might like this. No "gun" or anything, you just trigger things by getting close. Biggest issue is that on a couple puzzles I mistook shitty graphical anomalies for clues. For example the lighting and crappy boxy pillars made what looked like a triangle shape. I REALLY, for like 30 minutes, thought this was the clue to the puzzle when it wasn't even a clue. I;m fluctuating between a 3 and a 4 on this one. I liked it, but it was fundamentally not so amazing. Whatever, it gets a 4 because I enjoy "drop you in and let you figure it out" types.
